It is known to pack the fuse for a projectile in a sealed containerseparately from the projectile itself by screwing the base of the fuseinto a female thread formed in the lid of thel container so that, whensaid lid is positioned on the container, the fuse may be supported, apexdownwards, the container being Aafterwards sealed. The object of thepresent invention is to provide a simple form of container into whichthe fuse may be placed readily and which may be closed and sealed insuch a manner that, when required, the fuse may be removed without anyunscrewing.

To these 'ends and in accordance with this invention a cylindricalcontainer, the mouth of which is formed to receive a closure such as isdescribed and claimed in the specications of Letters Patent Nos. 23,843of 1912 and 105,547, is provided With a liner of cardboard or the like,the cylindrical Wall of which is stepped interiorly and intermediatelyof its length to receive a shoulder on the fuse, whilst an annulardistance piece, also of cardboard or the like, is provided to fit intothat part of the liner which is of greater diameter and to abut at oneof its ends against a second shoulder on the fuse and at, its other endagainst a packing disc of suitable material, such as indiarubber,located in the closure above mentioned and arranged to be pressedthereby against the mouth of the container.

The bottom or closed end of the container may be lined with a disc ofcardboard or the like, or a ring of indiarubber may be disposed thereon,whilst the periphery of the closure may be surrounded by a 'so-calledsealing-ring, i. e. a split ring of flat U-section the ends of which maybe united by a tongue and slot or other convenient form of junction.

The cylindrical portion of the lining may be formed as two separatetubes of such relative diameters, externally and internally and of suchrelative lengths that the shorter one will lit into the longer one and,when both said tubes are properly located in the container, present thestep on which the rst shoulder on the fuse may rest, whilst the upperend of the longer tube will be level with the top or mouth of thecontainer.

It is to be understood that the diameters and lengths of the container,of the cylindrical portion of the lining and of the annular distancepiece correspond with the diameters and lengths of the appropriate partsof the fuse so that when a fuse is placed in the container land theannular distance piece and closure are properly located, the fuse isheld immovably in the container, and the latter, moreover, ishermetically sealed so as to protect the fuse against the detrimentaleiects of atmospheric conditions, whilst the nature of the closure issuch as to enable the container to be opened with great facility to giveaccess to the fuse, when required.

The accompanying drawing shows one form of the invention in centralsectional elevation showing the parts in the positions they occupy priorto the application of the closing device.

As shown a is a cylindrical metal container,

closed at the bottom and the mouth of which is provided with a rim b toreceive a closure c such as is described and claimed in theSpecifications of Letters Patent Nos. 23,843 of 1912 and 105,547. Thecontainer a is provided with a liner of cardboard or the like,preferably waxed, constituted by a tube d within which is tted a shortertube e so that the liner as a Whole is stepped interiorly andintermediately of its length to receive a shoulder f on a fuse g, Whilstan annular distance piece h, also of cardboard or the like, is providedto t into the tube d, the distance piece h being intended to abut at itslower end against a second shoulder i on the fuse g and at its upper endagainst a packing disc It of suitable material, such as indiarubber,located in the closure c and arranged to be pressed thereby against themouth of the cylindrical container a.

The bottom or closed end of the cylindrical container a may be linedwith a nat ring of felt, m, as shown, or with a disc of cardboard or thelike and in some cases, especially if it be made of resilient materialsuch as indiarubber, it may be of such diameter as to extend rightacross the cylindrical container a and underlie the lower ends of thetubes d and e. The distance piece h, when the closure c is applied, ispressed by the packing disc Ic against the shoulder g' of the fuse g theother shoulder f of which is pressed against the top of the tube e andit is to be observed that before the closure c is applied the upper edgeof the distance piece h projects slightly above the level of the topedge of the container a. The upper edge of the tube d should lie at thesame level as the top edge of the container a if the packing m isarranged as shown in the drawing but it may project above said level,and the extent to which the distance piece h projects may be increased,if the packing m at the bottom of the containerV is of resilient'material and extends under the lower edge of the tube e.

n is a so-called sealing-ring of known type consisting of a split ringinitially of L-section and the ends of which are united by a tongue andslot connection at o, which is applied in that shape, after the closurec has been caused to engage the rim b, and, thereafter its lower edge isforced inwards by known means under the rim b so that ultimately thesealing ring 11. is of flat U-section.

In some cases the tubes fl and e may be integral with one another.Instead of a packing m under the lower edge of the tube e, a ring may bedisposed on its upper edge, e. g. by tting the ring on to the fuse g,but the arrangement illustrated is preferable.

I claim:

l. An improved container for a projectile fuse comprising a cylindricalcontainer having a closed bottom and an open mouth formed with anexternal bead, a cap having marginal gripping-nngers gripping said beadand a central resilient portion formed with a bulge, said cap beingreleasable from said container by pressing said bulge inwards, acylindrical liner extending substantially the full height of thecontainer formed interiorly with two different diameters, the larger atthe upper end and the smaller at the bottom end, whereby the inner wallof said liner is stepped intermediately of its length, a spacer sleevetting into the upper end of said liner which is of larger diameter, anda packing located in said cap, the step on the liner receiving ashoulder on the fuse, one end of said sleeve resting on a secondshoulder on said fuse and the packing located in said cap being pressedagainst the other end of said sleeve and against the mouth of thecontainer by said cap.

2. An improved container as claimed in claim 1, wherein said liner isconstituted by two telescoping tubes, the inner one of which is shorterthan the outer one and is closely and tightly fitted in the outer tube.

3. An improved container as claimed in claim 1, wherein said liner isconstituted by inner and -outer telescoping tubes, said inner tube beingshorter than said outer tube and terminating short of the bottom of saidouter tube, and wherein a packing is provided at the bottom of saidcontainer vand. within the lower end of said outer tube below. saidinner tube.

4. An improved container as claimed in claim 1, wherein said liner isconstituted by innerand outer telescoping tubes, said inner tube beingshorter than said .outer tube, and wherein a packing is provided betweenthe .bottom of said container and the adjacent bottom ends of saidinner` and outer tubes.
